I would hope that the number your hoping for is right I would prefer 10 myself due to the FA future in 9 months.
With six of the Rams OL'ers being involved in free agency in March of 2021 (Austin Corbett, Joe Noteboom, Brian Allen, Coleman Shelton, Chandler Brewer & Jamil Demby) along with the highly probable retirement of Andrew Whitworth the Rams will be in for some serious decisions & changes.
Just saw this:
Austin Corbett contract and salary cap details, full contract breakdowns, salaries, signing bonus, roster bonus, dead money, and valuations.

Leaving the Rams Ol with more than likely four (Havenstein, Edwards, Evans & Anchrum) as the known still under contracted OL'ers. UDFA Jordan Meredith is being considered as a center so he might have a good chance to end up on the PS along with OG Alaric Jackson. Brian Allen & Jamil Demby will be dangling in air to win a Ram 2021 roster spot if they do not begin to make serious improvements.
For right now the Rams Ol is sitting in an excellent situation most team could only dream about.
